Curtis ET-XXX Electronic Throttle
The Curtis ET-XXX provides a 0–5V throttle input and also Forward/Reverse
inputs (traction throttle) or Lift/Lower inputs (hydraulic throttle) for the 1297
controller. Wiring for the ET-XXX is shown in Figure 9. When an electronic
throttle is used, the Pot Low Check parameter (see Section 3
A, page 40) must
be set to Off; otherwise the controller will register a throttle fault.
There is no fault detection built into the ET-XXX, and the controller will
detect only open wiper faults. It is the responsibility of the OEM to provide any
additional throttle fault detection necessary.
